Abstract (en)
[origin: EP2854361A1] Disclosed herein is an apparatus for protecting traffic trend in a network of a control system using artificial communication. In accordance with an embodiment, the apparatus includes a communication terminal device installed in a network and configured to create and filter artificial communication. A communication server device determines whether to create artificial communication at a current time in the communication terminal device, requests a transmitting side-communication terminal device to create artificial communication, and requests a receiving side-communication terminal device to filter the artificial communication.
